NUT-LOCK FOR BEARINGS.

To all whom it may concern:

Be it known that we, EDWARD FLAHERTY and CHARLES WARRILOW, citizens ofthe United States, residing at Morea Colliery, county of Schuylkill, andState of Pennsylvania, and Hazleton Heights, county of Luzerne, andState of Pennsylvania, have invented certain new and useful Improvementsin NutLocks for Bearings, of which the following is a specification.

Our invention relates to improvements in nut locks for bearings and moreparticularly to improved nut locking means for bearings such as areordinarily employed as car pedestals and the like in which the nutsclamping the lower half bearing are secured against possibility ofworking loose.

A further object is to provide improvements of this character whichsecurely hold a plurality of nuts and which is effectually secured tothe bearing.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaim.

In the accompanying drawings: Figure 1 is a view in longitudinal sectionillustrating our improvements. Fig. 2 is a view in section on the line2-2 of Fig. 1. Fig. 3 is a perspective view of the nut locking memberdetached, and Fig. 4: is a perspective view illustratin a wedge key.

1 represents a section of car frame and 2 the upper half bearing memberfor the car axle (not shown).

3 is the lower removable half bearing member which is clamped to member2 and to support 1 by bolts 4 having heads 5 at their upper ends andnuts 6 at their lower ends. This is a conventional type of car bearingor pedestal, and in connection with which we employ our improved nutlock which consists of a plate 7 having a semicircular intermediateportion 8 to fit the lower half bearing member 3, and the ends of saidplate are extended in opposite direc- Specification of Letters Patent.

tions and provided with angular openings 9 conforming in shape to theshape of the nuts 6. The plate 7 conforms in shape to the shape of thelower half bearing member 3, and is adapted to be positioned against thesame with the nuts 6 in openings 9 preventing any turning movement ofthe nuts. A lug 10 is made integral with the lower half bearing member 3and projects through an opening 11 in the curved portion 8. A cotter pin12 may be projected through an opening 13 in the lug 10 and effectuallysecure the nut locking plate in position. Instead of the cotter pin 12,we may employ a Wedge key 14- as shown in Fig. 4.

In operation, after the nuts 6 are screwed home, the nut locking plate 7is positioned against the lower bearing member 3 with the nuts 6 in theopenings 9, and the plate 7 secured by means of the cotter pin 12 orwedge key 14. When in this position, the nuts will be prevented fromrotary movement, and hence cannot work loose due to vibrations and jars.

While we have illustrated our improvements in connection with two nutsat each side of the bearing, we would have it understood that theinvention is not limited to any particular number of nuts, and variousslight changes might be made in the general form and arrangement ofparts described without departing from our invention, and hence we donot limit ourselves to the precise details set forth, but considerourselves at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the appended claim.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:

The combination of two half bearings of semi-cylindrical form, havingerforated eX- tensions at their ends, bolts pro ected through saidextensions, and nuts on the lower ends of the bolts, of a plate having acurved intermediate portion and straight ends, said plate snugly fittingthe lower half bearing and having angular openings receiving the nuts,said plate at the center of its curved names to this specification inthe presence of portion having an opening therein, a pertwo subscribingWitnesses. forated lug integral With the lower half EDWARD FLAHERTY.bearlng and pro eet1n through the openin v I 5 in the plate, and a crosspin projected CHARLES WARRILOW' through the perforated lug,substantially as Witnesses: described.
